将解析后的T&Z时间戳转换为毫秒

function convertTimestampToMilliseconds(timestamp) {
  // Step 1: 解析T&Z时间戳
  const [datePart, timePart] = timestamp.split('T');
  const [year, month, day] = datePart.split('-');
  const [hours, minutes, seconds] = timePart.split(':');

  // Step 2: 将日期和时间部分转换为UTC时间
  const utcDate = new Date(Date.UTC(year, month - 1, day, hours, minutes, seconds));

  // Step 3: 将UTC时间转换为毫秒
  const milliseconds = utcDate.getTime();

  return milliseconds;
}

// 示例用法
const timestamp = '2022-01-01T12:00:00Z';
const milliseconds = convertTimestampToMilliseconds(timestamp);
console.log(milliseconds);
